Goodman GCVC91155DXAB Air Pressure Switch
The actual job of the air pressure switch is to sense whether the blower fan is blowing air. This pressure switch is part of the collection of safety devices in place to keep you safe from harm. Some pressure switches can have a manual reset, which, of course, means that it would have to be reset by hand in order for the system to begin normal operations again.
How is it Known when the Switch is About to go Bad
- Inaccurate electrical voltage reading from the switch.
- Furnace won't operate.
- Your system doesn't get to the correct indoor temperature.
